Reverse behavior of on-board LED3_R (LED_BUILTIN) of UNO Q

I substituted Pin 9 for LED4_G in the above sketch and that does not fade for me. It does compile and the LED with resistor does blink in a blink sketch, but will not fade with the below code:

#include<Servo.h> //V 1.3.0

Servo myServo;

#include<Arduino_RouterBridge.h>

byte i = 0;

void setup() {

pinMode(9, OUTPUT);

myServo.attach(9);

}

void loop() {

myServo.write(i);

delay(200);

}

The following sketch seems to be working. Check if it works for you.

#include<Servo.h> //V 1.3.0
Servo myServo;
#include<Arduino_RouterBridge.h>
byte i = 0;

void setup() {
  
  Bridge.begin();
  Monitor.begin();
  myServo.attach(8);

}

void loop() {
myServo.write(i);
i = i + 10;
delay(300);  

}

On my UnoQ, pin #8 has constant voltage to it regardless of code installed and when NO code is installed. That voltage is not variable There is no fade, with your above code for me on my board. It is a dim light constantly on pin 8. I have not found other pins that behave this way. I think we are talking about fading an LED in this thread. If you are trying to control a servo motor on pin 8, then I have not tried that as yet.

I have uploaded Sweep.ino from IDE Examples and the sketch is working well with SG90 Servo Motor connected at DPin-8. It also works wih DPin-9.

You have to increase i if you want to change brightness. And some delay

Do you have an UnoQ and have you tried an LED on Pin 8 ? If so, please show your sketch, thanks. I recommend a 220 Ohm resistor on the LED so it does not burn out. My pin 8 has constant voltage with or without a sketch.
